I don't get it, the Rockefeller family has an estimated net worth of $11bn today. That's for 174 members of this family or around $63m per family. While not a small amount, it's not outrageous either; especially that it's an old family, so they haven't really accumulated lots of wealth. You'd think compound interest would have made them own much more than that.

On the other hand, Bezos, a single person, has control of a $1.58T company and you are totally okay with it?
